Such features reduce the manufacturing complexity, cost, and overall size.

Abstract: Embodiments of the disclosure are directed to a coaxial connector with a translating grounding collar for establishing a ground path with a mating connector. The coaxial connector is configured to provide an electrical connection between two mating connectors. The coaxial connector includes a housing with a first conductor and a second conductor mounted within the housing. Further, the coaxial connector comprises a grounding collar mounted to the housing to provide a grounding of the coaxial connector with a mating connector that can discharge electro-static discharge build up before connections are established between the first and second conductors and a mating connector. Thus, the coaxial connector is grounded before establishing an electrical connection between the coaxial connector and a mating connector while also compensating for tolerance stack variability in the coaxial connector.

Abstract: Coaxial connectors with a grounding tube for altering a ground path with a conductor of the coaxial connector are disclosed. The coaxial connector comprises a grounding tube mounted within the connector housing and around at least a portion of a first conductor to initially establish and subsequently disconnect a grounding path between the first conductor and a housing of the coaxial connector. After contacting the mating connector, the first conductor moves, along with a first conductor housing, which moves a plurality of fingers of the grounding tube from the closed position to the open position. This disconnects the grounding path between the first conductor and the connector housing and establishes an electrical path between the first conductor and the mating connector. Thus, the coaxial connector is grounded before establishing an electrical connection between the coaxial connector and a mating connector.
